You definitely do not need that many attack skills, and if you do want to use that many, I would heavily recommend switching your elite to Zealous Vow. Otherwise you're going to run out of energy very quickly. And how come you have points in Earth Prayers but no skills that use it?
I'll second Slasher's recommendations - keep WS, MS, VS, and Heart of Fury. Get AoHM and Asuran Scan when you have EOTN and Factions. Definitely put those Earth points into Wind Prayers and get Attacker's Insight on there ASAP.
As for the last slot, a res or some sort of utility skill. I usually don't carry a res on my bar, and tend to have an open slot. Commonly I go /Mo for condition removal, /Me and use Mantra of Flame if I know I'll be fighting a lot of stuff that do fire damage, Lightbringer's Gaze if I'm somewhere with Margonites, or I just use Faithful Intervention as a cast-and-forget enchantment to help power Mystic Sweep, and also for an emergency self-heal should it ever be needed.
OgWkMkprKyi0FIzF3H0lBgMo4W4G is what I'm using at the moment (Scythe headpiece with +2 rune, +1 Mysticism, +1 Wind Prayers). The Inspiration points can be subbed into any other attribute you wish, I just have them there because I have Mantra of Earth on my bar at the moment. The e-management is simply ridiculously good and I'm able to constantly spam attack skills upon recharge. Whenever I get around to getting Asuran Scan I'll probably replace Radiant Scythe.
